Sarah melts some ice cubes
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Sarah initially tried throwing ice at the sauna stones, before building a bridge over the sauna stones to balance the ice over it, so it would melt and drip water onto the sauna stones. She made the sauna stones hiss in 8 minutes and 2 seconds, receiving 5 points.
